[0002] A screw feeder is a device commonly used in the plastic processing industry. It uses a screw to transport raw materials from a hopper to an extruder. It is an important component in a plastic production line. A screw feeder with a prompt function may be equipped with advanced sensors and control systems, which can monitor various parameters in real time during the operation of the equipment, such as material level, temperature, pressure, etc., and issue prompts or alarms when abnormalities are detected to ensure the stability and safety of the production process. The current screw feeders mainly transport raw materials through a hopper when in use, and then discharge the raw materials through a built-in screw. However, most screw feeders do not have the function of intermittent feeding. When too much raw material is accumulated, it is easy to cause the feeding port to be blocked, and it is difficult to transport the raw materials evenly. Utility Model Content

[0006] As a further solution of the utility model: the auxiliary plate is connected to the movable plate, and the column is slidably connected in the L-shaped plate.

[0007] As a further solution of the utility model: the fixing column is overlapped with the protrusion, and the positioning rod is connected with the motor phase.

[0008] As a further solution of the utility model: a concave plate is connected inside the funnel, and a drying cylinder is rotatably connected inside the concave plate.

[0009] As a further solution of the utility model: one end of the drying cylinder is connected to a rotating rod, the rotating rod is rotatably connected in the funnel, the rotating rod is externally transmission-connected with an anti-slip belt, and the rotating rod is connected to the positioning rod through the anti-slip belt.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The screw feeder with prompting function is provided with a collecting box, a bottom plate, an L-shaped plate, a turntable, a protrusion and a column. When the turntable rotates, the fixed column on the surface will contact the protrusion, and the protrusion will drive the auxiliary plate to move in the sleeve plate, and the auxiliary plate will drive the moving plate to slide in the funnel. When the collecting box moves to an appropriate position, the bottom plate will be separated from the supporting plate. After the bottom plate is turned over, the raw materials in the collecting box will fall down. When the fixed column contacts the L-shaped plate, the L-shaped plate will drive the auxiliary plate to recover. The screw feeder can realize the reciprocating movement of the collecting box in the funnel through the cooperation between the L-shaped plate, the protrusion and the fixed column, and can play the function of intermittent feeding, so as to avoid the phenomenon that the funnel is blocked due to excessive feeding of raw materials, and can evenly transport the raw materials.

[0012] 2. The screw feeder with prompt function is provided with a rotating rod and an anti-skid belt. When the second motor drives the positioning rod to rotate, since the positioning rod is connected to the rotating rod through the anti-skid belt, the drying cylinder and the positioning rod can rotate synchronously, and the drying cylinder can evenly dry the discharged raw materials to prevent the wet raw materials from agglomerating with the inner wall of the collecting box.

[0020] The funnel 2 is connected with a concave plate 8, and a drying cylinder 9 is rotatably connected in the concave plate 8. One end of the drying cylinder 9 is connected with a rotating rod 15, and the rotating rod 15 is rotatably connected in the funnel 2. The rotating rod 15 is externally connected with an anti-skid belt 23 for transmission. The rotating rod 15 is connected to the positioning rod 16 through the anti-skid belt 23. By arranging the drying cylinder 9, when the drying cylinder 9 rotates in the concave plate 8, the drying cylinder 9 can dry the unloaded raw materials to prevent the wet raw materials from agglomerating and causing blockage in the funnel 2.

[0021] The guide rod 13 is externally connected to a bottom plate 14, one side of the funnel 2 is rotatably connected to an L-shaped plate 17, one side of the funnel 2 is rotatably connected to a positioning rod 16, a sleeve plate 18 is connected to the side of the funnel 2, an auxiliary plate 19 is slidably connected inside the sleeve plate 18, a turntable 20 is externally connected to the positioning rod 16, two fixing columns 22 are provided on the front of the turntable 20, and a protrusion 21 and a column 24 are connected to the front of the auxiliary plate 19. By setting the sleeve plate 18, when the auxiliary plate 19 is affected by thrust or tension, the auxiliary plate 19 will slide inside the sleeve plate 18, so that the sleeve plate 18 plays a certain guiding role in the movement of the auxiliary plate 19, thereby preventing the auxiliary plate 19 from falling off during movement;

[0022] The bottom plate 14 is overlapped on the support plate 11, an inclined groove 7 is opened in the funnel 2, the auxiliary plate 19 is connected to the movable plate 10, the column 24 is slidably connected in the L-shaped plate 17, the fixed column 22 is overlapped with the protrusion 21, and the positioning rod 16 is connected to the motor 2 6.

When the collecting box 12 moves to the appropriate position, the bottom plate 14 will be separated from the support plate 11, and then the bottom plate 14 will rotate around the guide rod 13, and the raw materials in the collecting box 12 will fall accordingly. When the fixed column 22 contacts the L-shaped plate 17, the L-shaped plate 17 will drive the auxiliary plate 19 to recover, and the bottom plate 14 will overlap the support plate 11 and seal the collecting box 12. The unloaded raw materials will fall into the screw barrel 3, and the raw materials in the screw barrel 3 will be transported to the position of the discharge plate 25 by the motor 5.
